Yes it was the dos version, booting from the cd. However, I have just received the new hard disk and thought I would run the seatools again just to be sure, and it says the same - no hard drives found, and no controllers detected also.
Any ideas anyone? Does that suggest a controller issue, or just that seatools isn't working properly for some reason? I have set the bios to boot from legacy instead of UEFI, obviously.
Thanks
